A combination of sleep modes, peripheral control and other techniques can be used to maximize battery life. In this session, strategies for optimizing micro-controller energy profiles will be examined which will extend battery life while maintaining the integrity of the system. The techniques will be demonstrated on an ARM Cortex-M processor.

  • 14:00 – 14:45 – Network Insecurity: Simple Hacks of ARM Cortex-M Devices by Jonny Doin, CEO, Grid Vortex Systems

The IoT is a very new domain of a very old activity: Embedded Systems Design, with a twist: connection to the most toxic of environments, the Internet. One of the main concerns of the IoT is how to cope with the massive amount of unanticipated network traffic and problems. Malformed packets, corrupted messages, specifically targeted attacks, buffer overflow exploits, spoofing, stuxnet emulation messages, denial of service, fake OTAP, and other exploits and attacks can transform your IoT devices into something you did not design for. This situation demands several good practices and programming concerns regarding network safety and security into even the smallest of things. Buffer integrity checks, full parameters domain verification, message authentication, data path integrity verification, and crypto security are among the needed elements of a safe and secure IoT system, and can be implemented on nearly any Embedded System. Examples of simple attacks on ARM Cortex-M devices will be presented, including RET2ZP and buffer attacks.

  • 15:00 – 15:45 – RTOS Smackdown: 7 RTOSes in 45 Minutes! by 7 speakers

There are a lot of Real Time Operating System (RTOS) options out there. Which one is right for your embedded system? Do you even need an RTOS at all? In this feisty presentation, one industry expert will argue that an RTOS is superfluous to requirements, while another will contend that an RTOS is an invaluable, “must-have” asset, even if your embedded application performs only a handful of tasks. After the dust dies down, proponents of seven of the leanest, meanest, coolest, hottest contenders in the RTOS multi-universe will take it in turns to explain why their RTOS is the bestest of the best.

If you’d like to attend the conference you can register online. Access to the demo hall is free, unless you come without registration, in which case you’d have to pay $75 for entry. A pass is required for the full conference and access to sessions with the following pricing:
